LASTING-MACHINE.

Specification of Letters Patent.

Patented Oct. 17, 1911.

To all 'whom 'it may concern.'

Be it known that I, JOI-IN F. REID, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain Tmprovement-s in Lasting-Machines, of which thefollowing description, in connection with the accompanying drawings, isa speciiication, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relatesto lasting and tacking machines and has for itsobject to provide improved mechanism for working an upper over a lastand fastening it.

The invention is shown as embodied in a machine of the type known as thehand method lasting` machine for McKay work, an example of which isUnited States Letters Patent No. 423,922, granted March 25, 1890, onapplication of Gooding and Ladd.

A feature of this invention consists in novel mechanism for actuatingthe gripping devices to work the upper over the last and lay it in foldsor plaits and there hold it while the fastening mechanism advances intoposition to insert a tack for securing the upper.

A further feature of this invention consists in novel means forpresenting the tacks to be inserted. The novel mechanisms possess theadvantages of simplicity and economy of construction and durability aswell as special adaptation for the purposes for which they are devised.

These features and others, including certain details ofconstruction andcombinations of parts will appear in connection with the followingdescription of the illustrated machine and will then be pointed out inthe claims.

Figure 1 is a side elevation of so much of the machine shown in saidpatent as is needed to show this invention; Fig. 2. is a perspective ofthe grippers actuating mechanism; Fig. 3 is a perspective detail ofparts designed to be used alternatively with similar parts shown inFigs. 1 and 2 for rotating the grippers; Fig. 3a is a further detail;Fig. 4 is a plan in the plane of the line 44 of Fig. 1.

The grippers comprise a rigid jaw 14 and a pivoted jaw 16 which latteris formed with a lateral arm 161 located substantially midway betweenits upper and lower ends and extended through the holder for the jaw 14where it is pivoted at the back thereof at 162. A link 163 forms aflexible connection between the upper arm 164 of the pivoted jaw and itsactuator 15 which is a push rod. This link permits the jaw 16 to turn inan arc about the pivot 162. It will be observed that the link 163 formsone member of a toggle the other member of which is formed by the upperarm 164 of the jaw 16 together with the lateral arm 161. This second orlower member of the toggle has its fulcrum in the pivot 162 which is atone side of the line of pressure from the actuator 15 by which thetoggle is operated to close and open the grippers. This gives a long andadvantageously arranged leverage through which the jaw 16 is rockedtoward the other jaw to grip the work and hold it while the shoe upperis being pulled. The jaws 14 and 16, which together with other partsthat may correspond in general operation with the same parts shown insaid patent, are indicated by the same reference numerals as are thereinused. These jaws are mounted upon tele- V scoping shanks 13 and 15, thelatter of which has a ball head by which it is suspended from a socketblock 24 on the front end of a vertically oscillating lever 18 fulcrumedat 19 and actuated by a suitable cam on the cam shaft D. The shank 15extends above the lever 18 and is engaged by one arm of a rock-shaft 50which also receives motion from a cam on said shaft to depress the shank15 for closing the grippers which are herein opened by a spring 49 whichacts upwardly on a pin projecting laterally from the shank 15 through aslot in the sleeve 13. The spring rests upon a guide 3() through whichthe Shanks are vertically movable and which has also on its forward facea sleeve I) open at its upper side and supported at its opposite ends ina yoke 31 on a rod 32 which receives motion from a cam on theV shaft Dand a spring to overdraw the upper after it has been pulled upwardly bythe grippers. The grippers hold the upper until the advance thereon ofthe tack block S with its att-ached wiper 96 which receive their motionfrom the slide 84 also actuated from a cam on shaft D. The tack blockreceives tacks while in its retracted position shown in the drawingsfrom a raceway 210 which is pivoted at 211 and movable thereabout tobring either of its tack grooves 212 or 213 into position to permit thetack separator 214 to pick a long or a short tack and deliver it to thetack block. The relation and operation of these parts so far describedwill be well understood from the drawings and a fuller explanation maybe had from the specification of said patent.

The mechanism for imparting to the grippers their additional movementsfor forming folds or plaits to take care of fullness in the marginalportion of the upper at the toe and other convex curved edge portions ofthe upper receives its motions from the cam block 1 on the shaft D whichhas a groove in its front side as appears in Fig. 2. This groovereceives a roll on a connecting rod 2 guided in the frame as at 3 andconnected to a rocker 4 pivoted to a ixed part of the frame and having aguideway in its upper face transverse to its axis of rocking motion andreceiving a slide block 5 which can be positioned at either side of theaxis of thev rocker for transmit-ting motion in one or the otherdirection when the rocker is turned by the cam 1. The slide block isconnected, for positioning it as just stated, by a rod G with one arm 7of a rock-shaft 8, another arm 9 of which is connected by a rod 71 witha block which is confined in an oblique guideway 72 in the knee lever68, movement of which is limited adjustably in both directions by thestop screws 79. The slide block 5 is connected by an extensibleball-headed rod 20 with a ball on the end of a lengthwise adjustable arm21 of a rock-shaft 22, a clamp 23 holding the arm 21 on the rock-shaftand permitting its shifting to vary the extent of the movement impartedfrom rocker 5 to said shaft. The rockshaft has a second arm or sweep 25connected through suitable Y pivots with an extensible rod 26 leading toa plunger 51 that slides in the sleeve b and has in its upper face aV-shaped notch into which is received the V-shaped end of a springplunger 27, the tension of which can be varied by the sleeve nut 28threaded in a socket that projects forwardly from the gripper guide 30.The connection between the'grippers and the plunger formed by thewedge-shaped head of the yielding plunger engaging the walls of thenotch in the plunger 51 affords a very simple means of transmitting thethrust of the plunger yieldingly to the grippers for moving themlaterally to plait the upper and restoring them always to a centralposition after each lateral movement. Another rod or link 35 transmitsmovement from the sweep arm 25 to a vertically disposed lever 36fulcrumed at- 37 and having a socket at its upper end to receive a ballon rod 38. This rod may be connected with a rack bar 39 which engagesthe toothed side of the ball head 4() of the gripper shank 13 forrotating the grippers while they are being moved laterally as just abovedescribed for forming folds or plaits in the pulled upper. Alternativelythe ball head 40 may have anl integral arm 41 projected rearwardly asshown in Figs. 3 and 3ZL and formed to present one half of a socket fora ball on the end of the rod 38, the other half of the socket beingformed on a cover plate 42 attached to arm 41 by a screw 41a and a pin41h, while a distance stop is provided at 41C to prevent the socketbeing closed too tightly upon ball on rod 38. The arm 38 may be madeextensible, as shown, for angularly adjusting the grippers about theaxis of their Shanks. The lever 18 and the head block 24 may be formedwith an annular race for balls to support a ring 43 upon which the ballhead 40 directly rests for rendering more easy the rotation of thegrippers.

The shoe is supported bottom upward against the sole rest 12 which holdsthe last against displacement by the up-pull of the grippers. The shoeis also positioned laterally against the edge rest c while lasting therelatively difficult toe and heel portions where the pulling and tackingpoints are close together. This resthowever is in the way while lastingthe sides and shank portions of the shoe because of the contour of theside faces of the last., It is therefore arranged for sliding adjustmentforwardly and backwardly as explained in United States Letters PatentNo. 562,119 granted June 16, 1896, on application of George YV. Carterand a thin blade a is used for guiding at the shank and sides as thereinshown. The movement of the edge rest e is utilized for shifting theraceway to present to the separator 214 long tacks adapted to extendthrough and hold the relatively thick and plaited portions of uppermaterial at the toe and heel while those parts of the shoe are beinglasted and to present shorter tacks when the edge rest is back and thesides of the shoe are being lasted, where the upper materials are lessthick and are placed under less tension. The connection from the edgerest to the raceway in accordance with this invention includes a rackbar 52 attached to the rest and engaging the toothed end portion of anarm 53 of a short vertical rockshaft 54 journaled in a bracket of theframe and provided with a head 55 eccentrically bored to receive thethreaded upper end of the rockshaft and adjustably confined thereon by anut 58. This eccentric head is covered and inclosed by a hood or cap 56connected by a rod 57 with the side of the raceway. This connection hasthe advantage that it is economical to manufacture and durable and thatby adjustment of the eccentric on the rockshaft accurate positioning ofthe raceway grooves with relation to the separator T `can be effectedwhich is a material advantage over a cam or the like which requiresgreat precision in its formation. As the cap covers the eccentric itentirely excludes dust and dirt which insures ease of operation.

In the use of the machine the edge rest is brought forward to guide theshoe when the toe is to be lasted and thereby through the describedconnections shifts the raceway to cause long tacks to be presented tothe separator. rlhe grippers receive their usual pulling and overlayingmovements and, the knee lever being shifted to place the slide 5 at oneside of the axis of the rocker 4t, motion is transmitted from the cam lto the rockshaft arm 21 and from thence to the rockshaft 22 inproportion to the effective length of that arm which can be varied byadjusting it in the clamp 23 according as extensive or short plaits maybe desired in the upper. From the rockshaft motion is transmittedthrough the sweep armv 25 and connections to the plunger 51 and to the'arm 4t2 of the ball head 40 of the gripper shank.l

rlhe yielding plunger 25 transmits this motion through the coperatinginclined faces of the two plungers to the grippers which are therebylaterally moved while they are turned.
